Prerequisites

Setup Ansible: follow the installation guide to setup ansible on your machine.
Setup a remote machine with passwordless SSH login for the root user
Install passlib used for handling encrypted passwords when setting up a user
```
pip install passlib
```

Setup a user

Execute the following commands in the user-setup directory

Create a new hosts.ini file:
```
cp ../hosts.example.ini hosts.ini
```
Edit the hosts.ini file:
```
[deployment_host]
<host_name> ansible_host=<target_ip> ansible_user=<ssh_user> ansible_ssh_common_args='-o ForwardAgent=yes'
```
- Replace <host_name> with the desired hostname of the remote machine
- Replace <target_ip> with the IP address or hostname of the target machine
- Replace <ssh_user> with root

Verify that you are able to connect to the host using the following command:

ansible all -m ping -i hosts.ini

# Expected output:

# <host_name> | SUCCESS => {
#  "ansible_facts": {
#      "discovered_interpreter_python": "/usr/bin/python3.10"
#  },
#  "changed": false,
#  "ping": "pong"
# }

Setup user-vars.yml using the example file
```
cp user-vars.example.yml user-vars.yml
```

Edit the user-vars.yml file:

# name of the user you want to setup on the target host
username: ""

# password of the user you want to setup on the target host
password: ""

# path to the ssh key on your machine, eg: "/home/user/.ssh/id_rsa.pub"
path_to_ssh_key: ""

Execute the setup-user.yml Ansible playbook to create a user with passwordless sudo permissions:
```
LANG=en_US.utf8 ansible-playbook setup-user.yml -i hosts.ini
```
